A book is published in three volumes, the pages being numbered from I onwards.The page numbers are continued from the first volume to the second volume to the third. The number of pages in the second volume is 50 more than that in the first volume, and the number pages in the third volume is one and a half times that in the second. The sum of the page numbers on the first pages of the three volumes is 1709. If n is the last page number, what is the largest prime factor of n?

When the temperature of 4 moles of a gas was increased from 80^(@)C to 100^(@)C , at constant volume, the change in internal energy was 60J. What is the total heat capacity of the gas at constant volume ?

What is the total charge, in coulombs, of all the electrons in three gram mole o' hydrogen atom?

The line graph shows the production of product A and B (in thousands) during the period 2004 to 2009 and the second line Graph shows the percentage sale of these products. In the given line graph. what is the total sale of Product A in the year 2005 and 2009 taken together?

Equipotential lines arising from a static charge distribution has been shown in a certain region of space. (a) Draw the electric field lines starting from point A (b) If a charge is released at A, will it move along the field line passing through A? (c) How much work is done by the electric force if a charge moves from B to C? Is the knowledge of path important in this calculation?

What is the number of electric lines lines of force that radiate outwards from one coulomb of charge in vacumm ?
